The struct scarlett2_usb_volume_status matched the config space layout of a few volume controls that could be read together and were in fixed locations between Gen 2 and Gen 3 devices. Gen 4 devices have removed, moved, and new related controls, so this needs to be cleaned up. By adding SCARLETT2_CONFIG_MASTER_VOLUME (the only config item that didn't already have its own entry, because it is read-only), we can remove: - struct scarlett2_usb_volume_state, - #define SCARLETT2_USB_VOLUME_STATUS_OFFSET, and - scarlett2_usb_get_volume_status() and replace with calls to scarlett2_usb_get_config().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
